Technical Data; Delivery And Handling; Transportation; Storage - DAB FK Série Instructions Pour L'installation Et La Maintenance

For non-explosion proof pumps, the ambient temperature may exceed +40 °C for a short period.
For explosion-proof pumps, the ambient temperature on the installation site must be in the range from -20 °C to +40
°C.
Density and viscosity of pumped liquid
When pumping liquids with a density and/or a kinematic viscosity higher than that of water, use motors with correspondingly higher
outputs.
Flow velocity
It is advisable to keep a minimum flow velocity to avoid sedimentations in the piping system. Recommended flow velocities:
• in vertical pipes: 1.0 m/s
• in horizontal pipes: 0.7 m/s
Max. dimension and quantity of solids
Dimension from 50 a 100 mm, depending on pump size.
Quantity of suspended solid bodies max 1%.
Operating mode
Maximum 20 starts per hour.
FOR FURTHER LIMITATIONS OF THE OPERATING RANGE, REFER TO THE IDENTIFICATION PLATE.

Enclosure class
IP68. According to IEC 60529.
Insulation class
F (155 °C).
Operating pressure
All pump housings have a cast iron PN 10 discharge flange.
Dimensions
Discharge flanges are DN 65, DN 80, DN 100 or DN 150 according to EN 1092-2.
Pump curves
Pump curves are available via the internet on www.dabpumps.com.
The curves are to be considered as a guide. They must not be used as guarantee curves.
Test curves for the supplied pump are available on request.
It must be ensured that the pump does not operate outside the recommended operating range during normal operation.
Pump noise emission < 70 dB(A)
Sound power measurements were carried out according to ISO 3743.
•
Sound power was calculated at a distance of 1 metre according to ISO 11203.
•
The sound pressure level of the pump is lower than the limiting values stated in the EC Council Directive 2006/42/EC relating to
machinery.

3. DELIVERY AND HANDLING

3.1

Transportation

Before lifting the pump, check that the tools and equipment used for handling, lifting and lowering it into the
sinkhole are suitable for the weight to be lifted, efficient and complying with the applicable safety laws.
The weight of the pump is declared on the pump identification plate and on the label on the packaging.
Always lift the pump by its lifting bracket or by means of a fork-lift truck if the pump is fixed on a pallet. Never lift
the pump by means of the motor cable or the hose/pipe.
Make sure that the lifting bracket is tightened before attempting to lift the pump. Tighten if necessary. Carelessness
during lifting or transportation may cause injury to personnel or damage to the pump.
See FK Quick Guide for further details on handling.
3.2

Storage

During long periods of storage, the pump must be protected against moisture and heat.
Storage temperature: -30 °C to +60 °C. If the pump has been in use, the oil should be changed before storage. After a long period of
storage, the pump should be inspected before it is put into operation. Make sure that the impeller can rotate freely.
